Unsustainable management of land resources aggravates degradation. An accurate assessment soil erosion is needed to reduce the problem loss in highly fragile mountainous areas. Modeling impact LULCC on a vital process for watershed planning. This study aimed examine effect changing LULC upper Mile sub watershed, North Eastern highlands Ethiopia. It was done by quantifying and evaluating over ye...

Abstract The Euphrates-Tigris basin in Turkey suffers from sedimentation and erosion problems. purpose of this study was to estimate streamflow, sediment yield, identification soil erosion-prone areas for the Murat River Basin which is headwater Euphrates River, with Soil Water Assessment Tool (SWAT). model calibrated validated observed streamflow yield data obtained two gauging stations. stati...

Belawan watershed is one of the watersheds that have a primary role in North Sumatra Province. The flow crosses 2 (two) regencies/cities, i.e., Deli Serdang Regency and Medan City. In more detail, City located Hilir Sub-watershed. Several main rivers been polluted shallowed, as result people's habit littering river. People who live around significant sustainability river its ecosystem services....

This paper presents results on nutrient concentrations estimations in the Upper Tombigbee watershed (northern Mississippi-Alabama region, USA). It details the hydrological model development and its use for providing stream flow, runoff, and nutrient concentrations (total phosphorus, TP, and total nitrogen, TN) for subsequent biological studies. Geographical locations of data collection on fish ...

For the sustainable management of aquatic ecosystems, an integrated approach is required. This why watershed-based becoming increasingly popular instrument for improvement water quality. Water quality models serve as a central part watershed management. Predictive are valuable tools, but they usually complex infrastructures in terms both operation and software development. The aim this study to...

Abstract We report the effects of oxygen deficiency to electronic and magnetic properties SrCoO 3 calculated using spin-polarized Density Functional Theory. The correlation Co 3d orbitals are considered explicitly effective Hubbard U eff parameter. consists subtraction between value eV denote Coulomb interaction Hund’s coupling parameter J 0.95 eV. Our results show that localized character stro...

Landsat MSS and ETM+ images were analyzed to detect 25-year land-cover change (1976–2001) in the critical Taguibo Watershed in Mindanao Island, Southern Philippines. This watershed has experienced historical modifications of its land-cover due to the presence of logging industries in the 1950s, and continuous deforestation due to illegal logging and slash-and-burn agriculture in the present tim...

abstract spatial variability of soils makes difficult analysis of soil water flow phenomena especially in a large area such as a watershed. using scaling methods is a solution in variability problems. the objective of this study was to investigate the effect of the non-linear variability on performance of the scaling methods of richards’ equation for modeling infiltration in a watershed. the me...
